Default Chasing Air Leaks...DASH AIR SWITCH and CHAIR AIR SWITCH??

Hi everyone -- I have spent a few days looking for the answer, but cannot sort one out from all the hits I get on search...

My Front Airbags drop after abt an hour -- air leak somewhere, but do not hear it. New Pilot Valve. No leaks that bubble from levelers or pilots. Stair valve leaks if I don't fully retract and turn off master (which I do). So no leaks there.

Among the Last things I stumbled on -- I can feel air coming from the face of the switch on the dash that activates the tilt steering wheel. I would not be surprised if the other "air switches" are leaking similarly. There is one for each seat (side-to-side) and one for the suspension dump so 4 in total. CAN ANYONE TELL ME WHERE TO GET THOSE SWITCHES (part no.s, etc.).

I have seen others report that these activate solenoids, but mine have airlines to them directly, I think (I am not at the bus at the moment).

Default I Can't Post Pics....

I am not near the bus for a couple weeks.

These are all Toggle Switches. They all "PSSSSS" When activated.

---mTwo are on side walls and control the side-to-side of the Driver/Passenger seats. In one position, the seats are locked in place. In the other, they move side-to side.

---One is by driver's knee and controls suspension dump (i.e controls air to Pilot Valves).

---The one I KNOW is leaking is on the dash and releases the catch for the steering wheel tilt. In one position, the wheel is free to move forward or back. In the other it is locked in position. I suspect this is the only one I need to replace.

Default Mine are Pneumatic, not electric...

Hi Curt!

My switches are pneumatic -- The air comes to the switch (and in at least one case, out of the front of the switch!). I THINK it is this one based o another post:

https://www.clippard.com/part/M-TV-3S

Not at the bus, so cannot be sure (unless someone can confirm for me).

They might be available on Amazon, believe it or not!

That's what I used ( Amazon link here ). This was an exact replacement for the suspension dump switches on mine.
